Keep Spec Sand in Spec
A fine material screw is your workhorse for sand production. It separates unwanted silts and clays from your final product, then lifts clean sand up and out of the pool. It’s a simple design that does exactly what you need: wash, classify, and move material without slowing down the rest of your circuit.
Whether you're producing mason sand, concrete sand, or anything in between, this machine keeps your gradation tight and your operation moving. The Fine Material Screw is a straightforward tool that just works, day in, day out, load after load.
Need drier sand and higher stockpiles? Step up to the Aggredry® Washer with an integrated dewatering screen and fines recovery features.

Advantages
Outboard Bearing
Externally mounted pillow block bearing protects from water and contamination for longer service life and more convenient maintenance.
Load Zone Baffle
Calms the rush of incoming water to stabilize the pool, allowing more fines to settle and improving recovery efficiency.
Adjustable Wear Plate
Levels overflow to control water velocity and maximize fines retention across varying feed conditions.
Washback Nozzle
Directs spray toward the discharge to lift and drain sand that would otherwise remain saturated or idle near the outlet.
Same-Day Salable Sand
Our Aggredry Washer builds on the fine screw by integrating a dewatering screen and fines recovery in a single unit. The result is drier, cleaner sand (up to 20% less moisture), higher stockpiles, and increased yields.
- 8–12% moisture in final product for higher, drier stockpiles
- Dewatering screen reduces waiting for drying sand
- Removes unwanted lightweight silts for cleaner product
- Patented jet returns fines lost in dewatering to screw
- Easier integration with fewer transfer points and less complexity
It delivers cleaner, drier sand you can sell faster, with less rehandling and more product kept out of the pond.
